Newbie question about M-16 uppers

I am new to these forums, so Hi all. I have a question about the Ohio Ordnance Works M-16 uppers. They come without bolt, carrier, and charging handle. Can I use any bolt, carrier and charging handle? I assume its .223, but is there a special type I need? Thanks, Jeff

Is this going on a full auto M16 or a semi auto AR15? Different carriers, the full auto one in a semi could be bad news from a legal standpoint although it will function fine. Have to have the FA carrier to work in a 16 though. The bolts and charging handles are identical. Other than checking headspace for a particular combo, you can use any bolt in the right calber.

KernelKrink just about summed it up. AFAIK, and I'm no expert, my research tells me that you would be fine with an M-16 stripped upper. Fill it with an AR-15 Carrier(most carriers come complete with bolt) and a charging handle which is the same in an AR-15 or an M-16. Then you can put your completed upper on an AR lower. Unless you're class III, putting the internal parts of a miltarty M-16 into a civilian AR-15 will get you time in Club Fed! Savvy? The standard configuration for an M-16 or AR-15 is 5.56 NATO/ .223 Remmington!

One other issue is the Colt brand AR15 lowers use a different front pivot pin arrangement on at least some of their receivers. To adapt a milspec upper to those you need a special offset pin. No biggie, just something to be aware of. AFAIK all other brand lowers used the milspec front pin arrangement.
